I can tell you immediately what happens. You get an editor so powerful your underpants will rip in half and you will spontaneously self-combust. I'm not kidding, it has happened before.
For years, I've used Vim only when I had to. Basically, I knew only the few basic commands (the most precious being ":q" of course). Month-and-a-half ago, I've decided to take a closer look, and started learning it in depth. Now I know a lot more commands, but I am still a noob. Still, Vim is an amazing editor, and I don't even use EditPlus and such. There is simply no need to constrain myself to an advanced notepad, when I can have a Mercedes CLK GTR of editors. Please note that I'm not a car freak, I see them as means of transport. But this is not a car, it's a surreal pleasure apparatus.
So, check it out here: jVi - vi editor clone. Don't let the 1887-ish web design - or lack thereof - scare you away. Just download the package from SF, use the NetBeans plugin installer, restart and off you go - Vim in NetBeans!
Of course, it doesn't have all the features of Vim, but it does have enough features to be completely usable. So all of you were - old timers and weirdos - ranting about IDEs on the (now infamous) IDE thread can try one anyway.
If not, your bloody loss, innit? :)
